NEW YORK (Celebrity Hollywood) -- Blair Underwood's weird ride to becoming Stanley Kowalski onstage in "A Streetcar Named Desire" started four years ago with a dashed hope.

The actor had wanted to play Brick in an all-black Broadway revival of Tennessee Williams' "Cat on a Hot Tin Roof," but had lost the part to Terrence Howard, fresh off his Oscar-nominated turn in "Hustle & Flow."

"What are you going to do?" Underwood says, shrugging his shoulders.

Losing the role didn't sour him on the production, which he went to see one night at the Broadhurst Theatre. He was in the lobby during intermission when Stephen C. Byrd, one of the show's producers, spotted him and introduced himself.

Would Underwood be interested in playing Stanley in a multiracial production of Williams' other masterpiece on Broadway? Of course, came the answer. And, fittingly, years later, after shaking off a challenge from Denzel Washington, he now gets to do it and even at the same address - the Broadh urst Theatre. Underwood considers it fate.

"I'm a firm believer in what's yours is going to be yours, no matter what. And what's not yours is not going to be yours," says Underwood. So when the role of Brick went to Terrence, I was like, `It wasn't for me.' Stanley was for me."

Indeed, Stanley, that muscle-shirted brute once masterfully played by Marlon Brando, is now all his, opposite Nicole Ari Parker as Blanche and Daphne Rubin-Vega as Stella. Underwood considers it one of the ; stage's great roles.

"It's like Hamlet. It's like Othello. When it's all said and done, you close your eyes - hopefully at 90 years old plus - you look back and say, `That was in the body of work along the way,'" says the two-time Golden Globe nominee.

"I'm humbled and honored to really have the chance to do it because when you have a role like this that's not written f or a man of color, you don't know if you'll even get that opportunity."

Underwood at 46 seems to be enjoying a career that hasn't seemed to stop much since he burst onto the scene in the late 1980s in the film "Krush Groove" and the legal drama TV series "L.A. Law." He's coming off a whirlwind few years in which he was in the TV shows "In Treatment," "Dirty Sexy Money," "The New Adventures of Old Christine" and "The Event," where he played th e president of the United States. He's also got a book and a film planned for later this year.

"It's always busy because I want to keep it busy," he says with a smile.

The years have been kind to the man named by People magazine as one of the "Sexiest Men Alive" in 2004. When he walked through the lobby of The Associated Press recently, at least a few women did a double take and visibly grew weak.

Emi ly Mann, artistic director of the McCarter Theater in Princeton, N.J., fell under Underwood's spell when she sat down across from him for the first time during a table reading for "A Streetcar Named Desire."

"It's ridiculous how gorgeous that man is and how sexual he is without pushing any of it," says Mann, who directs the revival. "And that's important because that's where our Stanley moves from. That's his center - his sexuality."

Underwood has some big shoes to fill, and he's very aware of them. On Broadway, Anthony Quinn, Aidan Quinn, Alec Baldwin and John C. Reilly have all tackled Stanley, but the crown seems to rest on the head of Brando, who also appeared in Elia Kazan's classic 1951 film.

"There's always that ghost of the iconic production - Elia Kazan, Marlon Brando, Jessica Tandy. For me, I can't even deal with that. I mean, you really can't. You can't deal with something that's so beloved and so brilliant on every level," says Underwood.

"All you can do is instead of looking up and trying to grasp something that's already been done is look inwardly and as they did I'm sure at the very beginning, try to create this story and tell this story."

The producers of this "Streetcar" have one thing up their sleeves: Their production will likely feel the most like New Orleans. Besides havin g mixed-race actors reflect the population of New Orleans, the incidental music is being written by jazz luminary Terence Blanchard, a native of the Crescent City.

"New Orleans is a gumbo of culture and history and races - French, Spanish, African and all of those mixtures of people. So it's kind of appropriate that we would do this kind of production," says Underwood.

He adds that both Parker and Rubin-Vega both have lighter skin than he does, adding a sp 01;cial dimension to the story. "It makes sense specifically in the world of the South and New Orleans to have that perspective from Blanche to look down upon this dark-complexioned man. It will resonate in a unique way."

Underwood views his Stanley - in this show, the Polish last name Kowalski will be dropped - as a man-child, and the actor has clearly worked hard to reconcile his character's obvious failings with Underwood's natural sympathy for anyone he plays: "I do like Stanley very much. I don't like what he does. He's a flawed person, to say the least."

Mann says she's watched Underwood transform himself from a Carnegie Mellon-trained actor into an uneducated swine with no interest in poetry or art. "He knows that's the task and he can't wait to do that because he wants to stretch. You don't want always to play yourself. He's going to create his own Stanley that's to be different fr 1;m any other Stanley. It comes from a different place."

Though mostly known for TV, Underwood has frequently returned to the stage, a place he calls his "foundation." He was in a New York revival of "Purlie" opposite Anika Noni Rose, "Measure for Measure" at The Public Theater's Shakespeare in the Park series in 1993 and "Love Letters" with Alfre Woodard. He also created and starred in the one-man show "IM4: From the Mountaintop to Hip Hop," which was written by his brother Frank.

Underwood says these days he's just as happy staying off-camera, producing, directing or helping write projects. This month, he'll star in "Woman Thou Art Loosed: On the 7th Day," the second installment of Bishop T.D. Jakes' franchise. Underwood's fourth Tennyson "Ten" Hardwick book, "South by Southeast," will be out in the fall.

"I've been very fortunate, but a lot of hard work goes with that good fortune," he says.
